How to get and set data filter mode

Please follow below steps to get and set data filter mode

### 1. Get the DataFactory, DataConnectionManager and DataFilterManager instances

auto &dataFactory = telux::data::DataFactory::getInstance();
auto dataConnMgr_ = dataFactory.getDataConnectionManager();
auto dataFilterMgr_ = dataFactory.getDataFilterManager();

### 2. Wait for the Data Connection Manager and Data Filter Manager sub system initialization

bool dataConnectionSubSystemStatus = dataConnMgr_->isSubsystemReady();
if (!dataConnectionSubSystemStatus) {
    std::cout << "Data Connection Manager subsystem is not ready, Please wait" << std::endl;
    std::future<bool> f = dataConnMgr_->onSubsystemReady();
    // Wait unconditionally for data manager subsystem to be ready
    dataConnectionSubSystemStatus = f.get();
}
// Exit the application, if SDK is unable to initialize data manager subsystems
if (!dataConnectionSubSystemStatus) {
    std::cout << "ERROR - Unable to initialize subSystem" << std::endl;
    return EXIT_FAILURE;
}
bool dataFilterSubSystemStatus = dataFilterMgr_->isReady();
if (!dataFilterSubSystemStatus) {
    std::cout << "Data Filter Manager subsystem is not ready, Please wait" << std::endl;
    std::future<bool> f = dataFilterMgr_->onReady();
    // Wait unconditionally for data filter subsystem to be ready
    dataFilterSubSystemStatus = f.get();
}
// Exit the application, if SDK is unable to initialize data manager subsystems
if (!dataFilterSubSystemStatus) {
    std::cout << "ERROR - Unable to initialize subSystem" << std::endl;
    return EXIT_FAILURE;
}

### 3. Set data filter mode to enable

std::promise<bool> p;
int profileId = 2;
telux::data::IpFamilyType ipFamilyType = telux::data::IpFamilyType::IPV4;

telux::data::DataRestrictMode enableMode;
enableMode.filterAutoExit = telux::data::DataRestrictModeType::DISABLE;
enableMode.filterMode = telux::data::DataRestrictModeType::ENABLE;

auto status = dataFilterMgr_->setDataRestrictMode(enableMode,
         [&p](telux::common::ErrorCode error) {
        if (error == telux::common::ErrorCode::SUCCESS) {
            p.set_value(true);
        } else {
            std::cout << "Failed to set data filter mode" << std::endl;
            p.set_value(false);
        }
    }, profileId, ipFamilyType);
if(status == telux::common::Status::SUCCESS) {
    std::cout << "Set data filter mode Request sent" << std::endl;
} else {
    std::cout << "Set data filter mode Request failed" << std::endl;
}

if (p.get_future().get()) {
         std::cout << "Set data filter mode succeeded." << std::endl;
}

4. Get data filter mode

std::promise<bool> p;
std::string interfaceName = "rmnet_data0";

auto status = dataFilterMgr_->requestDataRestrictMode(interfaceName, configType_,
         [&p](telux::data::DataRestrictMode mode, telux::common::ErrorCode error) {
        if (error == telux::common::ErrorCode::SUCCESS) {
            p.set_value(true);
            if (mode.filterMode == DataRestrictModeType::DISABLE) {
                std::cout << " DataRestrictMode Disabled" << std::endl;
            } else if (mode.filterMode == DataRestrictModeType::ENABLE) {
                std::cout << " DataRestrictMode Enabled" << std::endl;
            } else {
                std::cout << " Invalid DataRestrictMode" << std::endl;
            }
        } else {
            std::cout << "Failed to get data filter mode" << std::endl;
            p.set_value(false);
        }
    });
if(status == telux::common::Status::SUCCESS) {
    std::cout << "Get data filter mode Request sent" << std::endl;
} else {
    std::cout << "Get data filter mode Request failed" << std::endl;
}

if (p.get_future().get()) {
         std::cout << "Get data filter mode succeeded." << std::endl;
}
